FRANK R. WEBER, OF TROY, NEW YORK, ASSIGNOR TO MOHAWK BRUSH COMPANY, OFALBANY, NEW YORK, A CORPORATION OF NEW YORK.

HAIRBRU SH.

Reference may be had to the accompanymg drawings, and the referencecharacters marked thereon. which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

The principal object of the invention is to provide a stronglight-weight back and handle for a brush having a substantiallysemicylindrical bristle-face.

Other objects will appear in connection with the following description.

Fig. 1 of the drawings is a top plan view of a hair-brush embodying myinvention. Fig. 2 is a side elevation of the same.

Fig. 3 is a cross-section of the same taken on the broken line 3-3 inFig. 2. Fig. 4 is a plan view of a blank of celluloid adapted to beformed into a back and handle for a brush embodying my invention. Fig. 5is a cross-section of the same taken on the broken line 5-5 in Fig. 4.

Referring to the drawings wherein the invention is shown in preferredform, 1 is the brush back which is semicircular in crosssection as shownin Fig. 3. and which has a handle, 2, formed by an integral longitudinalextension of the middle portion of the back.

The back and handle may be made in the form shown of wood, or metal. orof celluloid, vulcanite or other moldable material.

I prefer to make the back and handle of sheet celluloid, or similarsheet material which becomes plastic when heated.

In Fig. 4, I have shown a blank of sheet celluloid adapted to be moldedinto a brush back and handle adapted for carrying out my invention.

The portion of the blank adapted to form the back of the brush is formedwith side wings, 1, adapted when heated to be upturned in a suitablemold or die to semicircular form in cross-section as shown in Fig. 3,and when cool to retain this semicircular form.

If made of metal, the back and handle may be castin a mold.

If made of wood, .the back and handle may be cut and machined to thedesired form.

By forming the back channelor U-shaped by Letters Application filedAugust 27, 1925. Serial No. 52,830.

in cross-section I am able to produce a brush-back and handle of verylight weight. but of greatstrength and rigidity. This U shaped crosssection of the back also provides an arcuate finger receiving groovedefined in the space between the angularlydisposed longitudinal edges ofthe back which will facilitate the manipulation of the brush.

The bristles. project radially from the outer cylindrical surface of theback.

The bristles are preferably arranged in parallel rows oi tufts. parallelwith the axis oi said semi-cylindrical surface. The tufts of the variousrows are arranged in staggered relationship as clearly shown in Figure2.

The outermost-rows on opposite sides of the back project indiametrically opposite directions, and the intermediate rows project inoutwardly diverging relationship so that the outer ends of the bristlesin each row are spaced at distance from the corresponding ends of thebristles in adjacent rows.

The bristles are of substantially the same length and thus present asubstantially semicylindrical bristle-face for engagement with the hair.

In use the brush is engaged with the hair with a rocking or rollingmovement of the semicvlindrical bristle-face against the hair.

I do not wish to be limited to the constructions shown and abovedescribed. as for certain purposes of the invention, various changes maybe made in the form and arrangement of various parts of the device,without departing from the spirit of the invention, or the scope of theappended claim.

What I claim as new and desire to secure Patent is-- A hair brushcomprising an elongated body portion, one end thereof forming a handleand the other end thereof being relatively thin and having itslongitudinal sides curled upwardly to provide a brush back substantiallyU- haped in cross section, and a plurality of bristles arrangedinlongitudinally extending substantially parallel rows and projectingoutwardly from the convex face of said substantially U-shaped back, saidbristle tufts providing a brushing and combing surface which issubstantially at least semi-circular and the outer ends of i the tuftsof each row being spaced from the ends of the tufts of adjacent rowswhereby to provide a series of combing and brushing rows which may besuccessively presented to the hair by rotating the handle and backillsthe brush is also moved bodily over the 10 In testimony whereof, Ihave hereunto set my hand this 30th day of July, 1925.

FRANK R. WEBER.
